Nano-Phase KNa(Si<sub>6</sub>Al<sub>2</sub>)O<sub>16</sub> in Adularia: A New Member in the Alkali Feldspar Series with Ordered K–Na Distribution

Nano-Phase KNa(Si<sub>6</sub>Al<sub>2</sub>)O<sub>16</sub> in Adularia: A New Member in the Alkali Feldspar Series with Ordered K–Na Distribution

Alkali feldspars with diffuse reflections that violate <i>C</i>-centering symmetry were reported in Na-bearing adularia, orthoclase and microcline. TEM results indicate elongated nano-precipitates with intermediate composition of KNa(Si<sub>6</sub>Al<sub>2</sub>)O...
